Body confirmed as California college freshman who vanished in June

Updated 12:30 p.m. ET Saturday: A body discovered in Sacramento has been positively identified as 19-year-old Linnea Lomax, a distraught University of California, Davis freshman reported missing in June.

The Sacramento County coroner's office, which confirmed the body’s identity, said Lomax's death is under investigation, but foul play does not appear to be a factor, NBC television station KCRA reported.

The badly decomposed body was discovered 10:18 a.m. Friday near the shore of the American River by volunteers organized by the Klaaskids Foundation. It was in the Glenn Hall Park area, not far from where Lomax was last seen walking away from a mental health appointment, police said.

“We are grieved to report that we have just received confirmation that our search for Linnea has ended in sorrow,” members of HelpFindLinnea.org said in a statement posted on its website. Arrangements for a Celebration of Life service are being made, the group said.

According to her parents, the teen suffered a breakdown while studying for finals.

Police say Lomax was last seen at 1 p.m. on June 26, leaving an outpatient therapy center off Howe Avenue in Sacramento. She was considered missing and at-risk due to her disappearance being "inconsistent with her normal behavior patterns," police said.

She didn’t have her wallet or cell phone, Craig Lomax told NBC News in July. She had been prescribed medication for anxiety and depression, but she left her drugs behind, vanishing into California’s capital, he said.

Last month, a search party turned up a notebook belonging to Linnea Lomax near the American River bike trail.
